@Tyyppi_77 That sounds sensible. I'd add to that, if a mob is in the middle of motion and a player comes in near it for the first time, send its previous position+timestamp immediately along with its current/upcoming position+timestamp (don't wait for a client request; the server already has enough information to know this is the first time the client is seeing the mob, and should determine the client needs that extra bit of information on its own)

@TheMattbat999 beautiful :D

Actually it could just be a good general rule: whenever you tell a client where a mob is, if it is in motion, tell them where it was and what it's doing to perform the transition, plus timestamps. This means if a user's missed packets but they're still in the same spot, they get caught up on what's currently happening.

(that said, if someone's losing packets, they're always liable to see all kinds of weird stuff happening.)

2 adjacent slopes make a spike or a pit. You just die either way. Easy fix :P

Can you just make them a single long slope?

I'm trying to remember if I implemented stuff like this in the platformer code I wrote way back when and how I handled it......

@Tyyppi_77 Well i think ... its working now :) Thanks a lot (Dammit ... it was honestly pretty hard to implement this :D ) !

I really need to dig out that physics code I wrote to share it

Does anyone knows a good "weapon-upgrade" formula for mmos ? Each level should be more expensive of course...

@Tyyppi_77 Oh!! So what's happening is your player tries to move right, then collides with the solid tile just behind the ramp.

@Tyyppi_77 If the player is on a ramp, adjust their movement vector by 45 degrees.

Take the ramp's normal, use that to determine how far the movement vector is rotated.

Does anyone know where i could find somekind of formula for item upgrades ( weapons and co ? )

never made one... honestly ... i have no idea how i should make one :P

mess around with whatever seems fun

Well ok... im pretty lazy... but this should do it : baseCost + ((level + baseCost) x upgradeFactor)

Be careful that you end up with a game, not a math exam.

Usually these formulas are hidden though

you just see the upgrade costs etc

Having to calculate the most cost-effective upgrade is no fun (for normal people).

@Almo Thats right, but before i can show those costs... i need to calculate them, right ?

Many people disagree with you. I agree with you, but it's pretty common that people like this kind of min/maxing

Sure, people love min-maxing, but they also hate having to get out their calculator.

You need to go play EVE :D

You'd LOVE it

It's even F2P now.

As that guy explained you want people to have choices and make decisions, not have them solve an optimization problem. He explained that in diablo 3 when you compare 2 items almost always one of them is better in every way, but figuring out which one is difficult and requires some annoying calculations.

People should decide if they want extra burn damage or freeze the enemy for some time, not calculate dps.

hi

how are you

@Almo Once apt-get install eve works I'll consider it.

@Tyyppi_77 what are you working on today?

hey tyyppi

@nwp Diablo 3 shows you the DPS

no need to calculate

@Tyyppi_77 Cool. What language

Hmm does anyone know i could modify my formula to get even values ? (baseCost+((level * upgradeFactor)) ^2)

@Almo It does, but that's not enough. The problem is that the items add strength or whatever which changes the dps. Also strength scales with a logistic curve, so equipping an item with strength might mean you want to swap out another item that also gives strength. It gets really complicated.

@Tyyppi_77 What are they

@genaray add &~1 to the end :P

@nwp What ? :D Never saw this...

cool

In order to understand recursion, one must first understand recursion :P

That's an infinite loop, not recursion.

:D

@nwp say you have a function called recursion and the only thing it did is call itself... well that kinda is an infinite loop

unless the function has an exit condition

recursion(n)
{
    if(n == 0) return
    recursion(n - 1)
}

recursion(-1) //lol

that would still eventually stop

after the int flipped

Yup true

Unless you have a weird language like C or C++ where int overflow is undefined behavior.

@TheMaskedRebel no need to ping me if it's obvious you're responding to me

recursion(){ recursion()};

that is definitely infinite

Fun fact: Such an infinite loop is also UB in C++, so a compiler can just skip it.

It's allowed to remove it because it's UB =p

But then again almo's code doesn't really look like C++.

it's pseudocode

I'm watching a tutorial about networking

... on the network!!111

@TheMaskedRebel Got to go to events and parties.

:D

:D

@Tyyppi_77 Skip to episode 11

Be careful of youtube video tutorials. Most of them seem to be made by people with 2 weeks experience.

And if you are a beginner yourself you can't tell that most of the things they say is simply wrong.

@nwp do you have bad experience with the youtube tutorials

I can tell you that youtube videos on C++ that are from single people and not from conferences are utter garbage.

@nwp I'll advance that in some domains, even if you've been doing it for 5 years, you still might be doing it wrong, it's just that you or no one else noticed yet.

It may or may not carry over to whatever you are doing, but I would advice you to be picky when it comes to learning resources and try to find a reputable source.

@nwp I've watched the tutorial before

@AlexandreVaillancourt Thats exactly what I do... I optimize it later

@nwp Or multiple sources.

@TheMaskedRebel What is it that you do?

@AlexandreVaillancourt I follow tutorials and then I modify it for my own means

the word it meaning the code

@nwp He just gave me a disclaimer that he didn't have much experience

on the topic

@TheMaskedRebel Listen to him and move on.

Some people make these tutorials in order to learn the topic, not to teach. Good for them, bad for you.

@TheMaskedRebel Yeah, that's what tutorials are for :)

@nwp Did you ever watched videos on lynda.com?

No, never heard of.

@nwp You never heard of Lynda.com?

Right.

I really don't understand that lerp question.

Oh! Ok! That's a big-ish website offering video trainings. It now belongs to LinkedIn.

Oh, wait, maybe... [writes comment]

@AlexandreVaillancourt So basically youtube except you have to pay for the content? That doesn't seem like something I would want.

Youtube has plenty of good content already. I'm still behind on cppcon videos.

And arguably no matter what training videos they have they will not beat the big conferences.

The difference is that courses are complete on lynda.com, and are generally made by "professional" :)

But that answers my question :) I don't know exactly what I think about free VS pay courses...

@nwp Arguably that is only true for people with years of experience. If you are new to C++ watching cppcon videos will not help you, so there is a chance that lynda.com solves a real problem that is worth paying for.

@nwp I guess it depends on the topic, yes.

@AlexandreVaillancourt Do they do game dev

@TheMaskedRebel I've seen some about it, yes. I don't remember what it was about though.

I never liked videos where they code.

@nwp It really depends on what you are looking for. Some people might want the conferences or some people might want youtube.

@TheMaskedRebel Unless you are attending those are the same thing.

(That could have been phrased better but I hope you get what I meant)

@doppelgreener thanks!

@TheMattbat999 what kinda game are you making

@TheMaskedRebel a 3d (ish) retro styled RPG that takes place on a fantasy group of islands during the medieval era.

@TheMattbat999 What language are you using

Think The Elder Scrolls: Arena or DOOM for the graphical sytle

@TheMaskedRebel C#, with the Unity Engine.

@TheMattbat999 can I have the game

@TheMaskedRebel ?

@TheMattbat999 Is it on an open source repository

@TheMaskedRebel no.

I wanna have it at least half-way done before letting anyone actually play it. Plus, I wanna sell it when I am done, so going open source would be bad.

@nwp In java I had to actually write a manual function for checking weather an object is odd or even

@Tyyppi_77 I am listening to the tutorial in the background

@TheMaskedRebel That's the best way to slow down your own work and don't get what's being explained in the tutorial :)

not to mention I should be studying :P

Grade school and high school ends this week here, not sure about TheMaskedRebel's situation though.

@AlexandreVaillancourt I'm in england

@TheMaskedRebel There is no need to comment that you edited the post. The post owner will get a notification, and it will enter the suggested edit review queue so that others will be able to approve it.

@TheMaskedRebel Heh we've all been there :P

Does anyone here have any experience with networking

@TheMaskedRebel According to this documentation it should work in Java as I wrote it.

@AlexandreVaillancourt did you make this?

@TheMaskedRebel I don't understand the question? It says it's been released by IGDA, and it's from Ryan Morrison.

I've just crashed my laptop

with an infinite size on my window

@nwp If I do that I doubt that I would ever find a good tutorial

Click, start, code

that's a bot

My café's meal deal charges £4.95 for an apple

@doppelgreener get wallet out. Wallet looks at prices. Wallet dies

You should break into the place at night and add parenthesis.

Also good luck explaining to a police officer or judge what you were doing in case you get caught.

good idea

@nwp this is very important, i'm sure they'll understand

"As the first piece of evidence let me show you this operator precedence table..."

"Next, lemme show you my dead wallet due to your insane prices..."

hi @Jimmy

howdy

Howdy

hmmm. In your part of the world, does "howdy" rhyme with "daddy"?

Kinda, now I think about it.

(I am in good ole' Mississippi)

I would like to ask them some questions about networking

Don't ask such questions.

just ask the question on networking

How do I make the program to connect over computers on wifi.

do you want to connect a new device over wifi

how do I make the program span mutliple computers

or do you want to make a program that communicates with another program on another computer on the same Wifi network

@Jimmy Yup

hmmm

what language

That is the responsibility of network protocols such as IP.

@Jimmy java.

you may want a higher level networking library to do this

@Jimmy But how do I do it

but sticking to the basics, you can enumerate your computer's addresses

@Jimmy ?

Aannnnddd the conversation just flew straight over my head.

@TheMattbat999 networking

lmgtfy.com/?q=java%2Benumerate%2Bip%2Baddresses

@TheMaskedRebel have you looked at oracle's documentation for networking with Java?

You could look up the OSI model but you probably just want to open a socket for listening on one computer and another to connect with the other computer and you can send data across the network.

and then, as a slightly naive/dumb method, just try pinging all the other IPs in your subnet

and connecting to them on a port your application listens on

otherwise, there's stuff like upnp that helps you register things on a network to be found

nmap helps with finding services, but normally you don't want that because you can't really do much with an unknown service. You should instead know the service and connect to that, and if it isn't there then it isn't there.

yeah, nmap is weapons-grade "pinging everything on your network", hopefully your app doesn't need to do that

thanks for the help

I need to leave this chat

@Jimmy thanks, now I want to build an nmap enrichment facility

already done

shodan.io/search?query=Server%3A+SQ-WEBCAM

Come to think of it, it would be awesome if I could refactor my code via centrifuge.

here's all the unsecured webcam feeds on the internet

oh wait, most of those are secured now

I saw a SHODAN query a while back to find actual CCTV feeds

Been a while since I poked at that; haven't seen that particular site. I think I was using insecam.org

Those people should be severely fined (the ones who own the cameras).

yeah shodan is more just "nmap the internet" -- you have to figure out the search parameters yourself if you want to find particular things

ah, makes sense

I've seen similar distilled maps for unsecured wifi.

back when wardriving was still a thing.

yeah the wardriving maps are less easy to just build centrally, unless you have Google's resources

@TheMaskedRebel I knew the topic, but everything else that followed is what flew over.

it looks not as isometric as the last screen I saw

new prototype?

@Tyyppi_77 what don't you like about them?

the 45° is a bit sharp - does the code support other angles?

Maybe browse some sloped tilesets for inspiration? Super Mario World used 3 different angles.

Of course posting an image is easier than updating the engine to support them.

A different approach would be to just free hand something that looks interesting & then see how little you could get by with to implement it.

Don't sleep on that, they look uncomfortable

Yay! Added a real day-night cycle to my game!

Hooray!

Now working on a ranger-styled enemy....
